To all whom it may concern:

'lhisinvention relates toacomposition which possesses all the propertiesof hard vulcanized rubber, and is adapted to all the purposes for whichthat article is used, such as the manufacture of combs, buttons, &c.

My composition consists of boraX, shellac, glue, flour, linseed-oil, andmolasses, to which maybe added emery or other similar material,according to the articles to be produced. These ingredients are mixedtogether in various proportions, according to the requisite degree ofhardness or elasticity.

In order to dissolve the shellac I make a concentrated solution ofborax, and when the shellac is dissolved Iadd the glue, which may bepreviously soaked in water, and then the molasses and the otheringredients in the proper proportion. By a gentle heat the formation ofthe mixture is facilitated. From this composition I prepare buttons,combs, handles for knives and forks, and all such articles generallymade of hard rubber or vulcanite.

By mixing with my compound a suitable quantity of emery I can preparewheels or other tools for grinding metals or glass, tools, cutlery, andfor polishing various articles.
